OF THE GROOM LAKE/AREA 51 REGION
is a portion of the 58th edition of the Las Vegas Sectional Aeronautical
Chart from 11 September 1997. Sectional charts are distributed by
NOAA. A newer edition has since been published; therefore, this
chart is technically obsolete for use in navigation.
of Energy is the controlling authority for the R-4808 airspace.
Though this chart gives the airspace over Groom Lake the R-4808N
designation, the actual designation of the airspace over Groom Lake
over Groom Lake is continuously restricted to an "unlimited" ceiling,
which presumably ends somewhere before low Earth orbit.
